The advantages of package testing are as follows: Improve code maintainability: Encapsulation test can separate code logic from test logic, making code more modular and reusable. In this way, when the code needs to be modified or updated, only the corresponding test code needs to be modified, but not all test cases need to be modified. Improve code readability: Encapsulation test can separate the test code from the tested code, making the code clearer and easier to understand. The test code can be used as a document to help other developers understand the function and usage of the tested code. Improve code reliability: Encapsulation test can ensure the correctness of the tested code. The well written test cases can cover various boundary conditions and exceptions, thus improving the robustness and reliability of the code. Improve development efficiency: Encapsulated testing can automate the execution of test cases and reduce the workload of manual testing. In this way, developers can find and fix problems in code more quickly and improve development efficiency. The reason why we need to conduct encapsulation testing is to ensure the quality and stability of the code. Encapsulation testing can help us find and fix problems in code and reduce potential errors and defects. At the same time, package testing can also provide documents and examples to help other developers understand and use the code. Through encapsulation testing, we can improve the maintainability, readability, reliability and development efficiency of the code, thus improving the quality and effect of the entire project.
